Well, she was my default "if no one else readily makes themselves clear as a compatible" choice for the last one.
Also, thinking on it some more, dark horse for Inaba is Kisaragi because despite looking nothing like her (to me at least), we know Kisaragi is a singer so it fits with the idol thing. Also IIRC the "other" Kisaragi she accidentally contacted in the UFO mentioned being like nowhere on the map.
